|dw:1351326687906:dw| As you can see, the total horizontal force is $F_x=2F cos \theta \\ where\; cos \theta=\frac{3}{5}$

4. anonymous

|dw:1351326544993:dw| In X axis F=2T cos x where x=30/50=3/5[it is twice as OA and AC both components are same] so F=2*4*3/5=24/5=4.8N i.e (C)

But actually if i talk for exactness the information is wrong as elastic force is directly proportional to streching and it changes as we releases so integration is involved and lots more:)

6. anonymous

the answer is 8N

so u mean none of a , b ,c & d.................:0

8. anonymous

no ur right

9. anonymous

so its like this the resultant of both tension = force

10. anonymous

yup

A medal is just a way to say "Your help is appreciated". And don't you agree that it feels good to have someone say that to you?

18. anonymous
